GE TEYL3030B - 30 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

When resilience matters in electrical panels, the GE TEYL3030B 30A, 480V, 3-pole bolt-on molded case circuit breaker stands up to the challenge. Built to guard branch circuits against overcurrent and short-circuit events, it fits cleanly into panelboards and loadcenters where space and reliability are paramount.

Key advantages

• Secure bolt-on mounting: ensures a rigid, vibration-resistant connection to the bus, reducing movement that can lead to loose contacts and intermittent trips.
• Thermal-magnetic trip unit: delivers stable, repeatable protection by combining overcurrent and short-circuit sensing for predictable breaker response.
• High-voltage suitability: 480V rating makes it compatible with commercial and light industrial electrical distributions, not just residential circuits.
• Three-pole design: synchronized protection across all phases, helping to guard against phase-to-phase faults and unbalances in 3-phase systems.
• OEM-loadcenter compatibility: designed to work with matching GE loadcenters and other compatible panelboards, simplifying installation and replacements.
• Versatile applications: ideal for panelboards and loadcenters in residential, commercial, and light industrial settings needing robust 30A protection.
• Part and type details: Part Number TEYL3030B, Type Thermal-magnetic molded case circuit breaker, Mounting Style Bolt-on, Amperage 30A, Voltage 480V.

Common use scenarios:

• New installations in commercial buildings where 480V distribution feeds smaller branches require reliable protection without frequent maintenance.
• Retrofit projects in existing panelboards where a compact, bolt-on unit delivers quick, secure installation with strong bus connections.
• Industrial control panels that demand precise tripping behavior to minimize downtime from faults.

How this breaker protects your system

With a thermal-magnetic trip, the TEYL3030B responds to both overloads and short circuits, providing fast, predictable interruption only when needed. Its solid bolt-on mounting minimizes bus bar movement, reducing the risk of loose connections that can compromise protection over time.
